A method programs an implantable medical device such that it is configured for stimulating neural tissue by at least one electrode. The method includes: performing, by means of the implantable medical device, an evoked compound action potential (eCAP) threshold search by stimulating the neural tissue with test stimulation pulses； determining, based on the eCAP threshold search, an eCAP threshold amplitude and a coupling factor that is indicative of a coupling between the at least one electrode and the neural tissue； and generating a first set of stimulation parameters containing at least a stimulation amplitude that is determined in dependence on the eCAP threshold amplitude and the coupling factor.
